I'd say I'm middle of the road when it comes to age, but at least I knew what the computing world was doing at every age. Sometimes I talk to people older than me who have no clue about computing history, and while I do understand that it's not everyone's thing, there's so much in that history which can inform people today.
I started with the Sinclair ZX80 - 3.25 MHz, 1K of RAM, upper-case black and white 32x24 display, no floating point, and no ability to see what was on the display while the computer was running.
Going from that to a ZX81 / Timex Sinclair 1000 (they were the same except the ZX81 came with 1K and the TS/1000 came with 2K) was a dream - I had floating point with a rather excellent range of mathematical functions (Sinclair employed mathematicians to help write their BASIC, which was an excellent idea - Sinclair's BASIC kicked Microsoft BASIC's inconsistent ass), SLOW mode so I could see what was on the screen while the program ran, and a better design that made it easy to upgrade the system internally to 8K of RAM because the 16K RAM pack was prone to causing crashes if you moved the system.
This naturally led to the Amiga because Sinclair came out with the QL, which was neat - it had a 7.5 MHz m68008 processor (8 bit external bus version of the m68000), preemptive multitasking, bitmapped graphics, device abstraction, structured BASIC, and some halfway decent software which came with it. It was a poor person's machine for getting into the Amiga strata. Later, when Amigas were cheaper, I naturally got one.
The 1980s were significant for computing because it brought us from the tiny 8 bit worlds (CP/M, Apple, Commodore, Sinclair, Atari, PC-DOS, et cetera) through to the arbitrarily large 32 bit world. Learning about how each of the separate 8 bit worlds lived or died presents important lessons about growth and death - after all, everything nowadays is either some form of (free)Unix, Windows, or small.
This matters today because even the Amiga world, which is small, still exists and this is partly because of a very smart decision at the beginning to encourage people to write software for it. It was truly a programmer's machine. The fact that it's not too hard to port software from (free)Unix certainly helps.
People who don't understand the Amiga are usually people who don't remember history.
